The big difference for me is that Telestial's Global Riiing/United Mobile give you free incoming calls, in almost every country. Does T-Mobile have a card that gives you that? I guess that would really change the math.
Although the downside for Telestial's United Mobile is that the number is pretty expensive for the caller when you are receiving calls with it.
